Candles in glass boxes - perfect combination of cozy and contemporary. Using flameless/electric candles for this would be a good idea to not have to worry about melting wax oozing into the bottom of the glass box and onto the other decorative objects
A quilled flower set in the middle of this would make a pretty ornament! Just thread a cord through one of the inside of the tubes and pull it through the top, for a hanger. I would make single layers, if I were making an ornament.
